Jquery Datatables 1.9 with sAjaxSource columns not auto width to column contents.

I also posted this as a discussion on the datatables website.

Using the following code:
 
$(document).ready(function(){
 oTable = $('###URL.name#').dataTable({
 "bProcessing": true,
 "bServerSide": true,
 "bStateSave": false,
 "bAutoWidth:":true,
 "sAjaxSource":"#application.settings.absoluteURL#Framework/Generics/DB/CFM/dataTableAJAXForm.cfm?name=#url.name#"


 });
 
WHen I apply this the columns all come with even width. If i do not use sAjaxSource and simply put all the table contents on the page the column widths vary with the width of the data. Is there a way to do this with sAjaxSource without explicitly defining each column swidth? The table is used in a generic "template" page that will have a wide variety of columns. I dynamically print the column headers and footers to the page with a function (using ColdFusion 9 btw).
 
Thanks! Datatables is rad btw.
